Nibi Metrics
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Chilliwack River at Outlet of Chilliwack Lake
Chilliwack River - A vibrant mountain river that flows from Chilliwack Lake.
The Chilliwack River at the Outlet of Chilliwack Lake offers a critical glimpse into the dynamic hydrology of British Columbia's Lower Fraser-Coast region. With an expansive catchment area of approximately 335 square kilometers draining into this segment, the river emerges as a responsive player in the local ecosystem, shaped significantly by the seasonal melt of snowpack in the surrounding mountains.
The watershed context
Nestled within the rugged landscape of British Columbia, the Chilliwack River is influenced by its geographical location and the climate it endures. This river is part of a broader watershed system that includes notable peers such as the Alouette River and the Coquitlam River, all contributing to the intricate hydrology of the Lower Fraser area. Typically, the region witnesses a freshet driven by the melting snow from May to July, with glacier-fed systems maintaining elevated levels throughout the summer months. This seasonal rhythm contributes significantly to the river's flow patterns, showcasing the interplay between the environment and water levels.
Why the data matters here
Understanding the river's current flow data is paramount for various water management applications, including fishing, recreation, and environmental monitoring. As of today, the Chilliwack River's reading reflects its status compared to the historical median for this date, tracked over 49 years. This contextual comparison, provided by the Water Survey of Canada, allows for a more nuanced interpretation of the river's health, as it reveals insights beyond just the raw water elevation. Monitoring these fluctuations helps local stakeholders prepare for potential changes in biodiversity, water quality, and other ecological factors critical to the vibrancy of the Chilliwack River and its surrounding environment.
How this page is built
Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
